UFC on ESPN+ 5 takes place Saturday at The O2 in London and streams entirely on ESPN+ . In the featured main-card bout, former light heavyweight title challenger Volkan Oezdemir takes on Dominick Reyes . Oezdemir (15-3 MMA, 3-2 UFC) quickly rose to contention during an impressive 2017, but in 2018 lost in his title shot against Daniel Cormier and followed up with a submission defeat to Anthony Smith. Oezdemir will be looking to turn things around against Reyes (10-0 MMA, 4-0 YFC), who has finished eight of his 10 professional fights and looks to make a name for himself at Oezdemir’s expense
